Legally, your old employer can report the theft to the authorities, but they generally would not have the authority to directly inform your current employer. However, if the theft resulted in legal action and it became public knowledge, it is possible that your current employer could find out through other means, such as background checks or media coverage.
is my employer allowed to tell a lender that I have been using paid medical leave
Yes, and in many jurisdictions, a legal obligation also.
It depends on the circumstances. An employer can tell an employee what to do (provided it is part of the job and is legal, and safe). A police-officer can, provided the orders are justified and legal.
Yes. The legal implications would only be if they lied and caused you harm.
Yes it is relevant because your future employer would definitely like to know what kind of a person he is hiring.
No they can not, infact, if you can prove this happend, then you can sue them for conspiring to commit purgery..which happens to be a felony, if i were you, i would remind your employer of this, if they persist, then get legal council (a lawyer).
An employer can ask an employee if they are retiring as long as it is not done in a way that does not discriminate. It is not legal for an employer to tell an employee to resign because of his age. Also, an employee does not have to answer if his boss asks if he is retiring.
You can ask the flight crew and/or the airline itself, but they have no legal obligation to tell you anything.
Don't tell them. That's not something they have a right or obligation to know. All they are obligated to know is that you used to work at a particular job. In fact, if you tell them your work history and consent to them calling a previous employer all they can legally ask is if you used to work there. It will just look bad if you bring up dirt on any previous employer.
no you should sue
Yes, it is legal, but it it is rude and it wouldn't matter anyway. UK employers cannot fire someone for being gay.
