Is this your boss, SPB, or just a busybody?

If it's a busybody, just wait till the next time they start bothering you and say, "How is this your concern?"

If it's your boss, you can do various things: start keeping records of all orders given and of your work as you do it; go to the union to try to sort out; go to your boss's boss and seek help; if it's a big place seek reposting to a new area - and if none of this works, look for a new job.

Various herbs can be helpful, but be careful of clashes. St John's Wort, for example, traditionally doesn't go well with asthma medicine, and chamomile doesn't go well with asthma. I wouldn't personally use herbs without checking with the doctor.

I hope you sort this out.
