Yesterday during an important meeting with some clients, I accidentally broke a glass and ended up spilling champagne on a couple of people. First, the director practically burned a hole through me...

depending on your state, legally they might not even be able to deduct the cost of the cup from your pay. definitely look into the laws surrounding... that before you agree to pay any such thing.
frankly, it's embarrassing for them to be so desperate and broke to demand such a petty expense from you at all.
if the company is on such shaky legs that an, at most, $15 glass is breaking the bank, you need to be looking dor a new job anyway. their inability to deal with such an entry level setback is your red flag to reassess their capabilities of handling literally any other issue, regardless of fault, and their ability to provide stability for you. unfortunately, even if they cannot legally fire you for such a small and ultimately rather insignificant event, the fact that you feel like they are planning to fire you is your #1 sign to start searching for greener pastures. the company does not care about you - and if you have a gut feeling, your best bet is to quit while youre ahead.  more
