I am working for a academy - During my past teaching history there was a place that let me go for apparently breaching their online guidelines as I posted something silly online and a colleague coincidentally found it. So... a new company I work for has pushed me to state all the companies I worked for over X years and is seeking references from the above. They stated they needed 3 - 5 in total refs to be satisfied but are asking for more. The above organisation has notified that due to GDPR they require a former employee's permission to give references. So I re-directed the reference takers elsewhere to other workplaces of reasonable record. But this company won't let go. Now this company have said they need my consent and I'm not giving it, they want it! I am concerned that if a school have your consent they have carte blanche to give you a bad reference (whatever else they may have) and state reasons for dismissal. can I just refuse and ask them to use others?
