An example is on the London Underground , whose 2,000 cleaners are outsourced and despite playing a vital role protecting passenger safety every day, and during the current crisis, have vastly inferior conditions to their directly employed colleagues. As Labour mayor, Sadiq Khan can do more than just thank these hidden heroes – he can bring them back in-house and in doing set an example to the rest of the UK of how we truly value these and other essential frontline workers.Mick CashRMT general secretary • The late Sir John Sulston was right to point out that brain surgeons are held in high esteem, but would be unable to do their job without someone to clean the theatre. In so many ways we are all key to the smooth working of society.Audrey ButlerCheadle, Cheshire
Have a checklist before adopting a pet
• I don’t feel you have given a balanced perspective on the argument for Pets at Home employees to be acknowledged as key workers (Pets at Home under fire for coronavirus key worker claim for staff , 22 March). Closing Pets at Home during the coronavirus crisis would be like closing my local Tesco Express; my guinea pig would starve. I live in a city centre and my only access to pet food is through Pets at Home. If I can’t go to my local Pets at Home, and if the alternative home deliveries become severely delayed or disrupted, I will have a case of animal illness, neglect and cruelty on my hands.
Pet proof your house. To keep your pet healthy you should research what household products and foods can harm your pet. Make sure these are kept in secure locations so your pet cannot get into them.
Pets at Home is the only major pet store in my area. It is a lifeline for pets and owners at this time, and it is a thoughtless backlash from social media and other critics to suggest that pet supplies are non-essential.Lucy MatthewsNottingham
