I am a VP and oversee purchasing for a company . For several months this company has not been paying invoices yet has asked me to continue to place orders until we run out of credit . Over the last year 6 accounts have been sent to collections and from approx 200 accounts as of right now we are only able to order from about 20% of them . The other 80% of accounts are past due to varying degrees . Our accounting department does not return calls or provide status to me or the vendor . I have been asking for months about the health of the company and handing of past due accounts and I get no reply or a vague answer such as we will handle it or refer all accounting questions to this person ...
The worst part is that I have a relationship with most of these company's having established the accounts and negotiated pricing and worked together for some time . These vendors are emailing me and calling me constantly and my professional and personal reputation is suffering . I have a serious moral dilemma knowing that 90% of the orders we have placed the past few months have not been paid , and the few accounts not past due are top vendors I am particularly close with and have a several years past relationship with . They more than anyone I would hate to see not paid and my company has left me no other impression than they will not be paid . I cannot in good conscience send orders anymore that I do not believe will be paid . I sent my boss ( the CEO) an email today asking for status of the company health again and his plan for resolving the past due accounts. In my email I expressed that I would continue to do my job in terms of prospecting and compiling purchase orders however I would no longer be willing to send them once he approved them as I could not do so in good conscience unless I knew they were being paid or we had intention to pay them . I asked him to provide this to me before I would send them on . He replied stating that I worked for him and was I refusing to do my job and the duties required by not sending orders . I don't know what to do - I am fulling willing to do all aspects of my job except sending orders I don't believe we will pay based on our accounting practices of the last few months . I even expressed that I was willing to send them if he could brief me on the health of the company , future plan and our ability and intention to pay accounts . He completly ignored this and accused me of refusing my job duties . What is my legal obligation here ?
