It is an offence to have mobile phones turned on in the driving cab, yet Tocs are reliant on the driver having a company mobile phone.
The company I used to work for, had used some far-from reliable apps for tasks such a timesheets, booking on/off.
Therefore many phone calls to IT support to fix errant operations of the apps ( when not on duty / not being paid )IT will advise delete and re-install from scratch.
E-mail is God's Gift to office paper shuflers, those shufflers sending e-mails at all times of the day or week requesting reports/explaanations (again not on duty) , easy for them, 30-seconds to compose an e-mail , 30 minutes of work for us responding, and it makes them look oh-so productive "busy-work".
Another trick is sending trick phishing e-mails, you opened the e-mail , you should have guessed it is a trap, now you have to sit an online company training course "On-line security awareness"
I'm sure others will have their tales.
